In heutigen Kraftfahrzeugen ist es vielfach so, dass die Bedienelemente die Eingabe mehrerer unterschiedlicher Funktionen ermöglichen. Insbesondere in Kraftfahrzeugen, die mit einem Display ausgestattet sind, gibt es auswählbare Menüs, die mittels des Bedienelementes ansteuerbar und gleichzeitig auswählbar sind. Um das Navigieren und Auswählen der einzelnen Menüpunkte zu ermöglichen oder zu erleichtern, sind derartige Bedienelemente mit mehreren Kipp- und Drückfunktionen ausgestattet.In today's motor vehicles, it is often the case that the controls allow the input of several different functions. Especially in motor vehicles, which are equipped with a display, there are selectable menus that can be controlled by means of the control element and simultaneously selectable. In order to enable or facilitate the navigation and selection of the individual menu items, such controls are equipped with several toggle and push functions.
Ein gattungsgemäßes Bedienelement ist in der DE 103 42 335 A1 beschrieben. Beschrieben ist ein Bedienelement mit einer Dreh- und Druckfunktion, bestehend aus einem Drehschalter sowie aus einem Drucktaster, als bauliche Einheit zu einem Dreh- /Drucksteller. Ein Teil dieses Bedienelementes ist ein joystickartig aufgebautes Betätigungselement, das kippbar und drückbar im Gehäuse gelagert ist. Das Betätigungselement ist hierbei gegen die Kraft einer Feder in das Bedienelement hinein drückbar, wobei ein unterhalb des Betätigungselementes angeordneter Taster betätigt wird. Die Kippbewegung des Betätigungselementes wird mittels eines opto-elektrischen Systems bestehend aus einer Kulisse, die mit Lichtschranken zusammenwirkt, gebildet. Hierbei wirkt das Betätigungselement, das auch als Joystick beschrieben ist, mittels einer Kulisse auf zwei Lichtschranken, wobei die Lichtschranken in der Ruhestellung des Betätigungselementes gleichmäßig abgedunkelt sind. Die Lichtschranken sind hierbei um 90° zueinander versetzt, so dass beim Schwenken des Betätigungselementes es zu einer detektierbaren und elektronisch auswertbaren Veränderung des Lichtflusses in den Lichtschranken kommt.A generic control element is described in DE 103 42 335 A1. Described is an operating element with a rotary and printing function, consisting of a rotary switch and a pushbutton, as a structural unit to a rotary / pressure plate. Part of this control element is a joystick-like constructed actuator which is tiltably and pushably mounted in the housing. In this case, the actuating element can be pressed against the force of a spring into the operating element, wherein a button arranged below the actuating element is actuated. The tilting movement of the actuating element is formed by means of an opto-electrical system consisting of a backdrop, which interacts with light barriers. In this case, the actuating element, which is also described as a joystick, by means of a backdrop on two light barriers, the light barriers are darkened evenly in the rest position of the actuating element. The photocells are in this case offset by 90 ° to each other, so that when pivoting the actuating element it to a detectable and electronically evaluable change in the light flux in the light barriers comes.
Ein gattungsgemäßer Stand der Technik ist in der unveröffentlichten DE 10 2006 014 923.8 beschrieben, auf die hier ausdrücklich und in vollem Umfang Bezug genommen wird.A generic state of the art is described in unpublished DE 10 2006 014 923.8, which is hereby incorporated by reference in its entirety.
Die Aufgabe der Erfindung ist es eine sensorische Lösung für die Betätigungserkennung in einem Bedienelement mit vier Kipprichtungen eines Betätigungselementes sowie einer Erkennung der Drückbewegung bereitzustellen. Darüber hinaus ist es Aufgabe der Erfindung, eine konstruktiv einfache und kostengünstige Lösung für eine sensorische Betätigungserkennung zu entwickeln.The object of the invention is to provide a sensory solution for the actuation detection in an operating element with four tilt directions of an actuating element as well as a detection of the pushing movement. Moreover, it is an object of the invention to develop a structurally simple and cost-effective solution for a sensory actuation detection.
Die Aufgabe der Erfindung wird dadurch gelöst, dass das erste Mittel zur Erkennung der Kipp- und Drückbewegung aus einem opto-elektronischen oder elektronischen Mittel gebildet ist und das zweite Mittel zur Erkennung der Schaltschwelle aus einem schwenkbar im Gehäuse gelagerten Hebel gebildet ist, der mit einem Schaltelement zusammenwirkt, wobei das Betätigungselement mit dem Hebel mechanisch so gekoppelt ist, dass bei einer beliebeigen Auslenkung des Betätigungselementes der Hebel aus einer Ruhestellung heraus auslenkbar ist. Durch den erfindungsgemäßen Aufbau des Bedienelementes ist nun die Möglichkeit geschaffen, ein Betätigungselement in einem Bedienelement derart auszuführen, dass mit einfachsten konstruktiven Mitteln mindestens vier Kipprichtungen detektierbar sind. Insbesondere aus dem Zusammenspiel der Mittel zur Erkennung der Kipp- und Drückbewegung und dem zur Schaltschellenerkennung ist eine schnelle und eindeutige Kipprichtungs- und Schaltschwellenerkennung möglich.The object of the invention is achieved in that the first means for detecting the tilting and pushing movement is formed from an opto-electronic or electronic means and the second means for detecting the switching threshold is formed from a pivotally mounted in the housing lever, which with a Switching element cooperates, wherein the actuating element is mechanically coupled to the lever so that at a beliebeigen deflection of the actuating element, the lever from a rest position is deflected out. Due to the construction of the control element according to the invention, it is now possible to design an actuating element in an operating element such that at least four tilting directions can be detected with the simplest structural means. In particular, from the interaction of the means for detecting the tilting and pushing movement and for the detection of switching clamps a quick and clear Kipprichtungs- and switching threshold detection is possible.
Zur Erkennung einer Kippbewegung, das heißt einer Auslenkung des Betätigungselementes in zwei Richtungen wird eine Reflexionslichtschranke benötigt. So ist beispielsweise eine Nord-/Süderkennung dadurch detektierbar, dass einerseits die Reflexionslichtschranke in eine Richtung geschlossen und in die andere Richtung geöffnet wird. Durch das zweite Mittel zur Erkennung der Schaltschwelle, welches aus Hebel und mit dem Hebel zusammenwirkendes Schaltelement gebildet ist, ist hierbei die Schaltschwelle zur Erkennung der Betätigungsrichtung des Betätigungselementes definierbar.To detect a tilting movement, that is to say a deflection of the actuating element in two directions, a reflection light barrier is required. For example, a north / south detection can be detected by, on the one hand, closing the reflection light barrier in one direction and opening it in the other direction. By the second means for detecting the switching threshold, which is formed from lever and lever interacting with the switching element, this is the switching threshold for detecting the actuation direction of the actuating element definable.
Es ist somit eine berührungslose und reibungsarme und folglich auch störungsunempfindliche Sensorik bereitgestellt, mittels der die Aufgabe der Erfindung gelöst ist. Darüber hinaus bietet diese Lösung eine kostengünstige Ausführung, da sämtliche zur Erkennung der Kipp- und Drückbewegungen erforderlichen elektrischen Bauteile auf einer Leiterplatte angeordnet sind. Zusätzlich bietet der erfindungsgemäße Aufbau den Vorteil, dass die Kipprichtungserkennung von der Schaltschwellenerkennung entkoppelt ist, so dass sich diese elektrischen Bauelemente gegenseitig nicht beeinflussen und sich die Schaltschwellencharakteristik individuell auf die gewünschte Sensibilität einstellbar gestalten lässt. Dies bietet gleichzeitig den Vorteil, dass der erfindungsgemäße Aufbau eine hohe Toleranzverträglichkeit aufweist. Große Toleranzen bei den Kipprichtungserkennungsteilen sind ohne Bedeutung oder haben zumindest nur einen sehr geringen Einfluss auf die Funktionalität des erfindungsgemäß aufgebauten Bedienelementes, da selbst große Toleranzen im Aufbau des Bedienelementes durch eine Einstellung der Schaltschwelle eliminierbar sind.It is thus a non-contact and low-friction and consequently also insensitive to disturbance sensors provided by means of which the object of the invention is achieved. In addition, this solution offers a cost-effective design, since all necessary for the detection of tilting and pushing movements electrical components are arranged on a circuit board. In addition, the structure according to the invention has the advantage that the tilt direction detection is decoupled from the switching threshold detection, so that these electrical components do not influence each other and the switching threshold characteristic can be individually adjusted to the desired sensitivity. This also offers the advantage that the structure according to the invention has a high tolerance compatibility. Large tolerances in the tilt direction detection parts are irrelevant or have at least only a very small influence on the functionality of the control element constructed according to the invention, since even large tolerances in the structure of the control element can be eliminated by setting the switching threshold.

An den Zylinderstift 10 ist mindestens eine hebelarmartige Verlängerung 14 angeformt, die an ihrem äußeren Ende eine Reflexionsfläche 15 besitzt und mit den beiden Sendern und Empfängern 16, 17 eine Reflexionslichtschranke bildet.1 shows a basic structure of an operating element 1 is shown in a side view and in partial section. The operating element 1 consists of an actuating element 2, which is received in a ball guide 3 in a housing 4 pivotally and pressed. Supports 5, 6 carry on the one hand the housing and at the same time take up the printed circuit board 7. The supports 5, 6 extend from the bottom 8 of the housing 4 to the housing cover 9. Below the actuating element 2 and the ball guide 3, a pin-shaped extension is formed in the manner of a cylinder 10. At the lower end 11 of the cylindrical pin 10 and in the lever 12 V-shaped recesses are mounted between which a ball is clamped as a deflecting all actuations of the control element in a pivotal movement of the lever 12, which pivotally mounted in a bearing 13 in the housing. 4 attached, converted. On the cylinder pin 10 at least one lever arm-like extension 14 is formed, which has at its outer end a reflection surface 15 and with the two transmitters and receivers 16, 17 forms a reflection light barrier.
An einem äußeren Ende 18 des Hebels 12 ist ein Arm befestigt, der wiederum mit einem Sender 20 und Empfänger 21 gemeinsam eine Gabellichtschranke bildet und der sich im Wesentlichen parallel zum Zylinderstift 10 erstreckt. Der Arm 19 erstreckt sich hierbei ausgehend vom Ende 18 des Hebels 12 durch die Leiterplatte 7 hindurch zwischen die Lichtschranke 20, 21 , die auf der Leiterplatte 7 angeordnet ist. Wie in der Figur 2 dargestellt, ist das Betätigungselement 2 in Richtung des Pfeils P1 im Gehäuse 4 schwenkbar. Durch das Schwenken des Betätigungselementes 2 in Richtung des Pfeils P1 bewegt sich die Verlängerung 14 in Richtung des Gehäusedeckels 9 und verändert somit das durch die Reflexionslichtschranke 15, 16, 17 erzeugte Signal, da sich die Reflexionsfläche 15 vom Sender 16 und Empfänger 17 entfernt. Gleichzeitig kippt das Zylinderstift 10 um seinen Drehpunkt in der Kugelführung 3, wodurch der Hebel 12 mittels der Umlenkkugel um seinen Lagerpunkt 13 herum ausgelenkt wird. Diese Auslenkung oder Schwenkbewegung des Hebels 12 hat zur Folge, dass der Arm 19, sich aus dem Bereich der Lichtschranke 20, 21 heraus bewegt, wodurch ein eindeutiges Schaltsignal erzeugbar ist. Je nach Länge des Arms 19 und des Hebels 12 ist somit die Schaltschwelle der Lichtschranke 20, 21 einstellbar. Anzumerken bleibt hier, dass die Schaltschwelle natürlich auch durch jede geometrische Veränderung der Hebelmechanik, wie beispielsweise die Lage des Lagerpunktes 13, beeinflussbar und einstellbar ist. So ist mittels der Reflexionslichtschranke 15, 16, 17 die Kipprichtung in Richtung des Pfeils P1 und mittels der Lichtschranke 20, 21 und dem Arm 19 die Schaltschwelle einstellbar. Durch den erfindungsgemäßen Aufbau, ist somit eine berührungslose und störunempfindliche Sensorik bereitgestellt, bei der eine Entkopplung der Kipprichtungserkennung von der Schaltschwellenerkennung realisiert ist.At an outer end 18 of the lever 12, an arm is attached, which in turn forms a fork light barrier together with a transmitter 20 and receiver 21 and which extends substantially parallel to the cylindrical pin 10. The arm 19 extends from the end 18 of the lever 12 through the printed circuit board 7 through between the light barrier 20, 21, which is arranged on the printed circuit board 7. As shown in Figure 2, the actuating element 2 in the direction of the arrow P1 in the housing 4 is pivotable. By pivoting the actuating element 2 in the direction of the arrow P1, the extension 14 moves in the direction of the housing cover 9 and thus changes the signal generated by the reflection light barrier 15, 16, 17, since the reflection surface 15 of the transmitter 16 and receiver 17 away. At the same time, the cylinder pin 10 tilts about its pivot point in the ball guide 3, whereby the lever 12 is deflected by its deflection point around its bearing point 13 around. This deflection or pivoting movement of the lever 12 has the result that the arm 19 moves out of the region of the light barrier 20, 21, as a result of which a clear switching signal can be generated. Depending on the length of the arm 19 and the lever 12 thus the switching threshold of the light barrier 20, 21 is adjustable. It should be noted here that the switching threshold, of course, by any geometric change of the lever mechanism, such as the position of the bearing point 13, influenced and adjustable. Thus, by means of the reflection light barrier 15, 16, 17, the tilting direction in the direction of the arrow P1 and by means of the light barrier 20, 21 and the arm 19, the switching threshold adjustable. As a result of the construction according to the invention, a contactless and interference-insensitive sensor system is thus provided in which a decoupling of the tilting direction detection from the switching threshold detection is realized.
Wie in der Figur 3 dargestellt, reicht eine einzige Lichtschranke 15, 16, 17 aus, um zwei Kipprichtungen zu erkennen. In der Figur 3 ist das Betätigungselement 2 in Richtung des Pfeils P2 bewegt, wodurch der Abstand zwischen dem Reflektor 15 und den Lichtschrankendioden 16, 17 kleiner wird. Somit wird auch das Lichtschrankensignal beim Kippen in Abhängigkeit mit der Kipprichtung P1 , P2 entweder stärker oder schwächer. Zur Erkennung von vier Kipprichtungen ist eine weitere gleiche Lichtschranke 15, 16, 17, die im 90 ° Winkel zu der ersten Lichtschranke 15, 16, 17 auf der Leiterplatte 7 angeordnet ist, erforderlich. Der 90° Winkel gewährleistet in diesem Fall, das der Abstand in der Lichtschranke 15, 16, 17 für quer liegende Richtungen bezüglich in Bezug auf die weitere Betätigungsrichtung praktisch unverändert bleibt. Um eine Kipprichtung P1 , P2 zu erkennen muss die größte Signaländerung von beiden Reflexionslichtschranken 15, 16, 17 kurz vor oder nach dem Erreichen der Schaltschwelle ermittelt werden. Die Schaltschwelle wird, wie oben beschrieben, mittels der Gabellichtschranken 19, 20, 21 detektiert und eingestellt. Neben einem Kippen des Betätigungselementes 2 ist auch ein Drücken des Betätigungselementes 2 in Richtung des Pfeils P3 möglich. Während des Drückens, ändert sich das Ausgangssignal von beiden Lichtschranken 15, 16, 17 gleichzeitig in eine Richtung, so werden beispielsweise beide Ausgangssignale stärker. Diese Signaländerung in Kombination mit dem Signal der Gabellichtschranke 19, 20, 21 detektiert somit eindeutig die Druckfunktion des Bedienelementes 1. Anzumerken bleibt, dass neben den hier beschriebenen optischen Sensoren auch andere Arten von Sensoren für die beschriebene Auswertung einsetzbar sind, wichtig ist hierbei lediglich, dass es bei einer Bewegung P1 , P2, P3 des Betätigungselementes 2 zu einer auswertbaren Signaländerung kommt. Denkbar sind magnetische, kapazitive, induktive oder mechanisch wirkende Sensoren.As shown in FIG. 3, a single light barrier 15, 16, 17 is sufficient to detect two tilting directions. In the figure 3, the actuating element 2 is moved in the direction of the arrow P2, whereby the distance between the reflector 15 and the light barrier diodes 16, 17 is smaller. Thus, the light barrier signal when tilting in response to the tilt direction P1, P2 either stronger or weaker. For detecting four tilting directions, a further identical light barrier 15, 16, 17, which is arranged at 90 ° to the first light barrier 15, 16, 17 on the printed circuit board 7, is required. The 90 ° angle ensures in this case that the distance in the light barrier 15, 16, 17 for transverse directions with respect to respect to the further direction of actuation remains virtually unchanged. In order to detect a tilting direction P1, P2, the greatest signal change of the two reflection light barriers 15, 16, 17 must be determined shortly before or after reaching the switching threshold. The switching threshold is, as described above, detected and adjusted by means of the forked light barriers 19, 20, 21. In addition to a tilting of the actuating element 2, a pressing of the actuating element 2 in the direction of the arrow P3 is possible. During the pressing, the output signal from both light barriers 15, 16, 17 changes simultaneously in one direction, so for example, both output signals stronger. This signal change in combination with the signal of the fork light barrier 19, 20, 21 thus clearly detects the printing function of the operating element 1. It should be noted that in addition to the optical sensors described here, other types of sensors can be used for the described evaluation, it is only important in the case of a movement P1, P2, P3 of the actuating element 2, an evaluable signal change occurs. Conceivable are magnetic, capacitive, inductive or mechanically acting sensors.
Eine dreidimensionale Darstellung der Lichtschrankensysteme 15, 16, 17, 19, 20, 21 ist prinzipiell in der Figur 5 wiedergegeben. Zu erkennen ist die Lage der Verlängerung 14 mit den unter dem Reflektor 15 angeordneten Lichtschrankendioden 16, 17. Dargestellt ist eine Kippbewegung des Betätigungselementes 2 in Richtung des Pfeils P4. Diese Kippbewegung in Richtung Nord N und Süd S ist mittels einer Lichtschranke 15, 16, 17 detektierbar. Für die Kipprichtungserkennung in Richtung West W und Ost O ist ein zweites Lichtschrankensystem 15, 16, 17 erforderlich. Gleichzeitig dargestellt ist die Gabellichtschranke 20, 21 mit einer zwischen der Gabellichtschranke 20, 21 befindlichen Öffnung 22, durch die sich der Arm 19 durch die Leiterplatte 7 hindurch zwischen die Lichtschranke 20, 21 erstreckt.A three-dimensional representation of the light barrier systems 15, 16, 17, 19, 20, 21 is shown in principle in FIG. Evident is the position of the extension 14 with the arranged under the reflector 15 light barrier diodes 16, 17. Shown is a tilting movement of the actuating element 2 in the direction of arrow P4. This tilting movement in the direction of north N and south S can be detected by means of a light barrier 15, 16, 17. For tilt direction detection in the direction of West W and East O, a second light barrier system 15, 16, 17 is required. Shown simultaneously is the fork light barrier 20, 21 with an opening 22 located between the fork light barrier 20, 21, through which the arm 19 extends through the printed circuit board 7 between the light barrier 20, 21.
Eine alternative Ausführungsform ist in der Figur 6 dargestellt. Neben der Verwendung der Reflexionslichtschranke 15, 16, 17 ist es ebenfalls vorstellbar, die Kipprichtung des Betätigungselementes 2 mittels potentiometrischer Sensoren zu erfassen. Auf einer Leiterplatte 23 sind zwei potentiometrische Schichten 24, 25 aufgebracht, die mit zwei Schleifkontakten 26, 27 zusammenwirken. Die Schleifkontakte 26, 27 sind hierbei mit dem Zylinderstift 10 fest verbunden und über den Zylinderstift 10 elektrisch angeschlossen. Während des Kippens des Betätigungselementes in der Kugelführung 3 werden die Schleifkontakte 26, 27 über die potentiometrischen Flächen 24, 25 verschoben. Diese Widerstandsänderung der beiden potentiometrischen Sensoren 24, 25, 26, 27 ist auswertbar, so dass die Kipprichtungen Nord, Süd, West, Ost wieder eindeutig detektierbar sind. Das Erreichen der Schaltschwelle wird hierbei ebenfalls wiederum durch eine Gabellichtschranke 28, 29 mit einem dazugehörigen Arm eingestellt und erkannt.An alternative embodiment is shown in FIG. In addition to the use of the reflection light barrier 15, 16, 17, it is also conceivable to detect the tilting direction of the actuating element 2 by means of potentiometric sensors. On a circuit board 23, two potentiometric layers 24, 25 are applied, which cooperate with two sliding contacts 26, 27. The sliding contacts 26, 27 are in this case firmly connected to the cylinder pin 10 and electrically connected via the cylinder pin 10. During tilting of the actuating element in the ball guide 3, the sliding contacts 26, 27 are moved over the potentiometric surfaces 24, 25. This change in resistance of the two potentiometric sensors 24, 25, 26, 27 can be evaluated, so that the tilting directions North, South, West, East are clearly detectable again. Achieving the switching threshold is here as well again set and recognized by a fork light barrier 28, 29 with an associated arm.
Eine weitere Ausführungsform zur Erkennung der Kipprichtung beim Schwenken des Betätigungselementes 2 ist die Verwendung einer Kontaktfeder 30, wie sie in der Figur 7 dargestellt ist. Hierbei wird an dem Zylinderstift 31 eine Kontaktfeder 30 mit jeweils vier Kontaktarmen 32, 33, 34, 35 am Zylinderstift 31 befestigt, die wiederum mit elektrischen Kontakten 36, 37, 38, 39 zusammenwirken. Wie in der Figur 7 dargestellt, kommt es bei einer Auslenkung des Betätigungselementes 40 zur Schaltstellung, wie sie als punktierte Linie 41 in der Figur 7 wiedergegeben ist.Another embodiment for detecting the tilting direction when pivoting the actuating element 2 is the use of a contact spring 30, as shown in FIG. Here, a contact spring 30 with four contact arms 32, 33, 34, 35 attached to the cylindrical pin 31, which in turn interact with electrical contacts 36, 37, 38, 39 on the cylindrical pin 31. As shown in Figure 7, it comes with a deflection of the actuating element 40 to the switching position, as shown in dotted line 41 in Figure 7.
Wird nun das Betätigungselement 40 in die punktierte Richtung P5 verschoben, so wird der Kontakt 38 von dem Kontaktarm 34 kontaktiert, so dass eine eindeutige Kipprich- tungserkennung in diesem Fall in Richtung Westen W, erkannt. Die dadurch erzeugten Ausgangssignale sind für die Erkennung des Schaltvorgangs ungeeignet, da hier relativ große Toleranzen auftreten, sie reichen aber zur eindeutigen richtigen Kipprich- tungserkennung aus. Die Schaltschwelle wird auch in diesem Fall mittels einer Gabellichtschranke 42, 43 erkannt.If now the actuating element 40 is displaced in the punctured direction P5, the contact 38 is contacted by the contact arm 34, so that a unique tilt detection recognition in this case in the direction west W, recognized. The output signals generated thereby are unsuitable for the detection of the switching operation, since relatively large tolerances occur here, but they are sufficient for unambiguously correct tilt detection. The switching threshold is detected in this case by means of a fork light barrier 42, 43.
Das erfindungsgemäße Bedienelement 1 bietet somit den Vorteil, dass für alle Kipprichtungen Nord N, Ost O, Süd S und West W eine absolut gleiche Schaltschwelle einstellbar ist. Dies wiederum ermöglicht ein genaues Abstimmen der Schaltschwellen- detektion auf die Haptik des Bedienelementes 1 , wie dies in der Figur 8 mit den Verläufen der Schaltschwellen Ausgangssignale 44 klar ersichtlich ist. Die Ausgangssignale 44 für die Schaltschwellen L3 liegen alle auf einem einheitlichen Niveau. In das Diagramm sind neben dem Verlauf der Schaltschwellencharakteristik der Gabellichtschranke auch der Verlauf der beiden Reflexionslichtschranken 15, 16, 17 eingetragen. Beispielhaft wird hier der Verlauf in der Kipprichtung P4 oder Nord N, nach Figur 5, erläutert. Bei der Bewegung des Betätigungselementes 2 in Richtung des Pfeils P4 oder in Richtung Nord N ändert sich der Wert des Lichtschrankensystems L1 nur geringfügig, der Verlauf der Linie L1 ist nahe zu konstant, wohingegen sich der Wert des Lichtschrankensystems L2, die die als Linie L2 in das Diagramm eingezeichnet ist, als deutlicher Ausschlag des Signals im Verlauf des Diagramms zeigt. Der Verlauf der Schaltschwellencharakteristik L3, hier als Linie L3 wiedergegeben zeigt für alle Kipp- richtungen einen identischen Ausschlag. Umgekehrt ist dies in Kipprichtung W1 hier äußert sich der Verlauf der Linie L3 nur geringfügig, wobei er nahezu konstant bleibt. Der Verlauf der Kennlinie L1 zeigt hingegen einen deutlichen positiven Ausschlag, wie im Diagramm mit 45 gekennzeichnet. The operating element 1 according to the invention thus offers the advantage that an absolutely identical switching threshold can be set for all tilting directions North N, East O, South S and West W. This, in turn, allows an accurate tuning of the switching threshold detection on the feel of the operating element 1, as can be clearly seen in the figure 8 with the curves of the switching thresholds output signals 44. The output signals 44 for the switching thresholds L3 are all at a uniform level. In the diagram, in addition to the course of the switching threshold characteristic of the fork light barrier and the course of the two reflection light barriers 15, 16, 17 registered. By way of example, the course in the tilting direction P4 or north N, according to FIG. 5, will be explained here. During the movement of the actuating element 2 in the direction of the arrow P4 or in the direction north N, the value of the light barrier system L1 changes only slightly, the course of the line L1 is close to constant, whereas the value of the light barrier system L2, as the line L2 in the diagram is drawn, as a clear deflection of the signal in the course of the diagram shows. The course of the switching threshold characteristic L3, reproduced here as line L3, shows for all tilting characteristic L3. an identical rash. Conversely, this is in tilting direction W 1 here, the course of the line L3 manifests itself only slightly, while it remains almost constant. The course of the characteristic curve L1, however, shows a significant positive deflection, as indicated in the diagram by 45.
